By flashing its LED lights hundreds of times per second, Apple Watch can calculate the number of times the heart beats each minute your heart rate. When your heart beats, the blood flow in your wrist and the green light absorption is greater. Apple Watch uses green LED lights paired with lightsensitive photodiodes to detect the amount of blood flowing through your wrist at any given moment. This technology, while difficult to pronounce, is based on a very simple fact: Blood is red because it reflects red light and absorbs green light.

In treadmill tests, the Apple Watch and Mio Fuse were the most accurate. None of the four devices achieved the accuracy of a chest strap monitor. But as people exercised, the accuracy diminished.
